Actress Angie Harmon broke down in tears as she recalled the moment an Instacart driver shot her beloved dog dead in 'self defense'.

The Law & Order star wept as she described hearing the screams of her youngest child after she realized what had happened.

'You don't ever forget that sound,' Harmon told Good Morning America. 'I heard my youngest screaming. I just heard her say, did you just shoot my dog? I was like, what?'

Harmon's beagle mix Oliver was shot and killed at her North Carolina home during what should have been a routine transaction through the grocery delivery app. The driver claimed he was attacked, but Harmon said there was no evidence of this.
